But following fears fellow cons disgusted by his crime were plotting to mete out prison justice, SPS bosses moved him to a prison in Kilmarnock. 

The 22-year-old murdered Karen after offering her a lift as she left Sanctuary nightclub in Glasgow's west end. 

He battered her with a spanner and strangled her before trying to dissolve her body in caustic soda. 

Describing Pacteau as a loner, one source told the Scottish Sun: “He was in real danger. He’d become a target to some dangerous people who are well aware of what he’s done. 

"But he will probably face the same reaction."

Karen, who was a qualified nurse, had come to Glasgow to further her career. She originally graduated from the University of Limerick before moving to Essex to work as a nurse.

She came to Scotland because she wanted to "specialise" and get a Masters degree at Glasgow Caledonian University which is based in city centre.
